About Fanregratinib

Fanregratinib (HMPL‑453) is a novel, highly selective and potent inhibitor targeting FGFR 1, 2 and 3. Aberrant FGFR signaling has been found to be a driving force in tumor growth, promotion of angiogenesis and resistance to anti-tumor therapies. Abnormal FGFR gene alterations are believed to be the drivers of tumor cell proliferation in several solid tumor settings.

HUTCHMED currently retain all rights to fanregratinib worldwide.

About IHCC with FGFR2 Fusion/Rearrangement

IHCC is one of the subtypes of primary bile duct cancer. In China, an estimated 61,900 newly diagnosed IHCC occurred in 2015 and the overall IHCC incidence increased by 9.2% per year between 2006 and 2015.[1] FGFR2 fusion has been reported to have a prevalence of 10-15% in IHCC patients.[2]^,[3]
